Radiant Barrier Finished Attic

If you re searching for does attic radiant barrier work or is radiant barrier worth it this article will help.

Radiant barrier finished attic.

A radiant barrier reduces the radiant heat transfer from the underside of the roof to the other surfaces in the attic. If your house doesn t have continuous ridge and soffit vents so it s trapping excess heat in the attic that s a very cost effective improvement. Radiant barriers are utilized to reduce summer heat gain in attics and help to improve the efficiency of green building envelopes. But radiant barrier maybe but it s kind of hard to tell because there s a lot of claims of energy efficiency but it s very difficult to prove it out.

The best way i have seen to describe this effect is it s like putting your home or office under a shade tree. Unlike traditional thick layers of insulation radiant barrier is a thin reflective material. But a radiant barrier is very effective addressing another way to transmit heat. You still need ventilation addresses convection and insulation addresses conduction.

Also the greater the temperature difference between the sides of the radiant barrier material the greater the benefits a radiant barrier can offer. When installed properly radiant barriers can reflect up to 95 of the radiant heat off the attic. A radiant barrier works best when it is perpendicular to the radiant energy striking it. A radiant barrier can lower heat transfer from attics to the building below keep the attic space cooler and lower cooling costs by up to 17 in warmer climates.
